LAMP-OSCILLATOR.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed February 23, 1909. Serial m. 479,64

To all whom it may concern:

Be it known that I, GEORGE PRINTUP, a citizen of the United States of America, and resident of Lynchburg,v in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Lamp-Oscillators, of which. the f ollowing is a specification.

This invention relates to certain new and useful improvements in means for supporting a lamp on an automobile or other vehicle.

It has for its objects among others to provide simple and cheap means for constantly vibrating or oscillating the lamp in a plane across the path traversed by the vehicle. The construction is such that this oscillatory motion is obtained by connection with some moving part of the vehicle, as, for instance, the axle, although the invention is in no wise restricted to the means for deriving the motion from the vehicle or the part ofthe vehicle from which the motion is transmitted.

A further object of the invention is to provide simple and ellicient means whereby a plurality of drives are obtained whereby the speed or frequency of the oscillation may be Varied according to required conditions or circumstances.

A further object of the invention is to prostance, during the daytime or at other times notwithstanding the continuous movement of the parts by which the lamp is given its oscillatory motions when desired. h Still a further object of the invention is to provide against wabbling or motions of. the amp due to the movement of the vehicle other than the positive oscillation obtained bythe mechanism soonto be described.

Other obj eclts and advz-intages of the invention will hereinafter appear and the novel features thereof Willbe particularly pointed out in the appended claims. The invention is clearly illustrated in the accompany'ing' drawings, which, with the numerals of reference marked thereon, form apart of this invention, and in whiclw" Figure 1 is a side elevation of a lamp and oscillator with a portion broken away, showing my improvement. Fig. 2 isa lan view thereof with the lamp removed. l ig. 3 is a sectional detail ofthe oscillator with parts in elevation, Fig. 4 is a sectional detail of a,

portion of the lamp and its support,showing the modified form of means for holding the lamp against oscillation when desired.

Like numerals of reference indicate like parts tln'oughout the several views.

Referring to the drawings, 1 designates a casing" within which the operati 11g parts are contained. This has a removable cap 2 held in place by any suitable means as screws 3 or the like engaging openings 4 in the casing.

5 is a shaft having a bearing in a boss 6 on. the casing and this shaft is designed to derive its power, so as to be coi'itinuously rotated during; the movement of the vehicle,

In the present inin any suitable manner. stance, l have chosen to show a flexible shaft 7 ofany suitable nature and which is designed to be connected in any convenient or well-knowi'i way with some moving part of the vehicle, as, for instance, the axle, so that the said shaft shall be coi'itinuously revolved as long as the vehicle is in motion. Any other means, however, may be emplovod for imparting, such continuous rotation to the shaft and such means may derive power from any moving part of the vehicle.

8 is a worm gear on said shaft 5, which shaft is extended and has a bearing in a boss 9 on the cap 2 of the casing, as seen best :in Fig. 3, On this shaft 5, within the casing, is a cam 10 which may be given any desired shape suitable for the purpose, that herein illustrated having been iound a most cllicient one.

(ill

1] 1s a shaft mounted to oscillate in a 'suitable bearing 12 in the casing and a suitable hearing 13 on the cap, and upon this shaft is the oscillator 14 which is prefcrablyof the shape seen in Fig. 2, and between the arms 15 and 16 of-which the cam 10 operates. This shaft 11 is shown in Figs. 1 and 3 as h aving its upper end olygonal in form, as shown at 17, and thipo ygonal end. is received 'in. a

socket 18 in the depending collar 19 of the lamp 20, which latter may be otherwise of any well-known or approved form of construotio i.

The operation will heron-(lily understood VVith the parts constructed and arranged as shown and described and the lamp locked in position so as to take the movements given to the oscillator, and the shaft 5 being connected by the flexible shaft, or other means, with some moving part of the. vehicle, as the vehicle is put in motion, the shaft 5 is continuouslyrotated and this continuohs rota-' Y receive continuous motion. during the movetio'n moves the cam 10 continuously in one direction, but this continuous rotation of the cain imparts to the oscillator 14 a back and forth'or oscillatory motion, as will be readily understood. The worm 8, in this instance, serves no function, and, it but one drive is desired, this worm need not be present. This worm, however, "serves an important function in that when it is desired to change the speed or frequency of the oscillation of the member 14 and consequently of the lamp, it is accomplished as follows' 21 is a shalthaving a bearing ina boss or the like 22 on the casing and extending, in this in stance, at substantialljright angles to the shaft 5. This shaft l iewise is designed to ment of the vehicle by any suitable means as the flexible shaft 7 connected with the axle or some other moving part. On this shaft is aworm 23 which meshes with the-worm gear 8 so that when motion is given to the shaft 21, this motion, through the medium of the worm 23 and the worm gear 8, is imparted. to the shaft 5 and consequently to the cam 10 and to the oscillator 14. The oscillations given by the rotation of the shaft 21, through the medium of the'worm' and worm gear will be much slower than when the drive is direct through the medium of the shaft 5 alone. The same flexible shaft or power imparting means may be used for both drives, as will be readily understood. It is to be noted that by the particular construction and formation of the cam and 0'scillator, the contact points of the two arms 15 and 16 are always 0 posite each other and these two arms are a ways in contact at the same time with the cam so that there is absolutely no lost motion and hence no Wabbling of the parts can take place.

In order to be able to throw out the lamp when necessary parted thereto-the oscillatory motion of the member 14, any suitable means may be pro vided, for instance, as seen in Fig. 1, wherein VII 24 is a lever pivoted at 25 on an arm or projection 25' on the lamp body and designed to engage in a notch or the like 29 in a boss 2? rigid with the shaft 17 so that when the lever is in engagement with the notch, the boss 19 and the member 27 will be locked so asto move together, but, whenthe lever is thrown so as to bring its lower end out of engagement with the notch 26,- the member 27 oscillates not imparting itsmotion to the lamp, it being understood that the socket 18 is circular so as to allow the-portion 17 of the shaft to turn therein, without giving motion to the so that it shall not have im scenes into which the end of the lever is engaged when it is desired to lock the shaft and lamp so that the latter will be oscillated.

From the above, it will be seen that l have devised a simple, yet durable and efficient form of mechanism for giving continuous oscillatory motion to the lamp, and,while the structural embodiment of the invention as herein disclosed is what I at the present time consider preferable, it is evident that the same is subject to changes and modifications in detail, proportion of parts etc, and l there-- fore do not wish to restrict n ell to the do. tailed construction herein disclosed, but reserve the right to make such changes, variations and modifications as come properly within the scope of the protection prayed.
